617. Narrated Sālim bin 'Abdullāh: My father said that Allāh's Messenger ﷺ said, "Bilāl pronounces Adhān at night, so keep on eating and drinking (Sahūr) till Ibn Umm Makṭūm pronounces Adhān." Sālim added, "He was a blind man who would not pronounce the Adhān unless he was told that the day had dawned."
